ABSTRACT:
A device that reproduces signals recorded on a recording medium includes a unit that forms a tracking error signal from pilot signal components recorded in the signal being reproduced. A controller controls the tracking error signal forming unit so that the tracking error signal forming unit operates under reduced power during part of the signal reproducing operation. The tracking error signal forming unit uses a digital filter and the controller controls the digital filter to vary its characteristics.
